Jeremiah 34:13-16

13thus says Adonai, the God of Israel: “I made a covenant with your fathers in the day that I brought them out of the land of Egypt, out of the house of bondage, saying:

14‘At the end of seven years you are to set free every man his brother that is a Hebrew who has been sold to you and has served you six years; you are let him go free from you.’ But your fathers did not obey Me, nor inclined their ear.

15Now you had repented, and had done that which is right in My eyes, by proclaiming liberty everyone to his neighbor. You even had made a covenant before Me in the House where My Name is called.

16But you turned around and profaned My Name, and made everyone his servant and his handmaid, whom you had let go free at their will, return, and you brought them back into subjection, to be your servants and handmaids.”
